When a site does not work with LastPass, I want to be able to disable LastPass completely for that site without losing my work.
Example: I spent 15 minutes in the business cards designer on Staples.com when I needed to save my work and log in. LastPass could not handle the login screen and interfered when I typed the username and password manually. To overcome this, I had to disable the extension completely in the browser extension manager, navigate away from the designer and back (fortunately, I didn't lose my work), and copy the username and password into notepad from LastPass desktop. This happened in Microsoft Edge, the latest version, so it's basically Chrome.
DuckDuckGo has this feature for its extension. I realize it is hard because the extension hooks the browser element event chain, but please try.
